[origin: WO9712804A1] In an aircraft (1) according to the invention the engine drives a blower and the compressed air is used to increase the lift of the wing (18) and the canard (22) using jet flap propulsion. The airfoil profile has maximum thickness just forward of the control surface device (12) which has large included trailing edge angle and large leading edge radius. The control surface device hinge (17) is positioned close to the mean line (19) of the plane, and air slots (10) in the plane are blowing the control surface device.
